Conifers are gymnosperms. They are cone-bearing seed plants. All living conifers are woody plants which are perennial. Most are trees; some are shrubs. They are the Division Pinophyta or Coniferophyta. [1] [2] Living conifers are all in the order Pinales.
Temperate coniferous forests sustain the highest levels of biomass in any terrestrial ecosystem and are notable for trees of massive proportions in temperate rainforest regions. [1] Structurally, these forests are rather simple, consisting of 2 layers generally: an overstory and understory.
conifer, any member of the division Pinophyta, class Pinopsida, order Pinales, made up of living and fossil gymnospermous plants that usually have needle-shaped evergreen leaves and seeds attached to the scales of a woody bracted cone.
coniferous forest, vegetation composed primarily of cone -bearing needle-leaved or scale-leaved evergreen trees, found in areas that have long winters and moderate to high annual precipitation. The northern Eurasian coniferous forest is called the taiga or the boreal forest.
Tropical and subtropical coniferous forests are a tropical forest habitat type defined by the World Wide Fund for Nature. These forests are found predominantly in North and Central America and experience low levels of precipitation and moderate variability in temperature.
